+
+# 1. Who can contribute to Synapse?
+
+Everyone is welcome to contribute code to [matrix.org
+projects](https://github.com/matrix-org), provided that they are willing to
+license their contributions under the same license as the project itself. We
+follow a simple 'inbound=outbound' model for contributions: the act of
+submitting an 'inbound' contribution means that the contributor agrees to
+license the code under the same terms as the project's overall 'outbound'
+license - in our case, this is almost always Apache Software License v2 (see
+[LICENSE](LICENSE)).
+
+# 2. What do I need?
+
+The code of Synapse is written in Python 3. To do pretty much anything, you'll need [a recent version of Python 3](https://wiki.python.org/moin/BeginnersGuide/Download).
+
+The source code of Synapse is hosted on GitHub. You will also need [a recent version of git](https://github.com/git-guides/install-git).
+
+For some tests, you will need [a recent version of Docker](https://docs.docker.com/get-docker/).
+
+
+# 3. Get the source.
+
+The preferred and easiest way to contribute changes is to fork the relevant
+project on GitHub, and then [create a pull request](
+https://help.github.com/articles/using-pull-requests/) to ask us to pull your
+changes into our repo.
+
+Please base your changes on the `develop` branch.
+
+```sh
+git clone git@github.com:YOUR_GITHUB_USER_NAME/synapse.git
+git checkout develop
+```
+
+If you need help getting started with git, this is beyond the scope of the document, but you
+can find many good git tutorials on the web.
+
+# 4. Install the dependencies
+
+## Under Unix (macOS, Linux, BSD, ...)
+
+Once you have installed Python 3 and added the source, please open a terminal and
+setup a *virtualenv*, as follows:
+
+```sh
+cd path/where/you/have/cloned/the/repository
+python3 -m venv ./env
+source ./env/bin/activate
+pip install -e ".[all,lint,mypy,test]"
+pip install tox
+```
+
+This will install the developer dependencies for the project.
+
+## Under Windows
+
+TBD
+
+
+# 5. Get in touch.
+
+Join our developer community on Matrix: #synapse-dev:matrix.org !
+
+
+# 6. Pick an issue.
+
+Fix your favorite problem or perhaps find a [Good First Issue](https://github.com/matrix-org/synapse/issues?q=is%3Aopen+is%3Aissue+label%3A%22Good+First+Issue%22)
+to work on.
+
+
+# 7. Turn coffee and documentation into code and documentation!
+
+Synapse's code style is documented [here](docs/code_style.md). Please follow
+it, including the conventions for the [sample configuration
+file](docs/code_style.md#configuration-file-format).
+
+There is a growing amount of documentation located in the [docs](docs)
+directory. This documentation is intended primarily for sysadmins running their
+own Synapse instance, as well as developers interacting externally with
+Synapse. [docs/dev](docs/dev) exists primarily to house documentation for
+Synapse developers. [docs/admin_api](docs/admin_api) houses documentation
+regarding Synapse's Admin API, which is used mostly by sysadmins and external
+service developers.
+
+If you add new files added to either of these folders, please use [GitHub-Flavoured
+Markdown](https://guides.github.com/features/mastering-markdown/).
+
+Some documentation also exists in [Synapse's GitHub
+Wiki](https://github.com/matrix-org/synapse/wiki), although this is primarily
+contributed to by community authors.
+
+
+# 8. Test, test, test!
+<a name="test-test-test"></a>
+
+While you're developing and before submitting a patch, you'll
+want to test your code.
+
+## Run the linters.
+
+The linters look at your code and do two things:
+
+- ensure that your code follows the coding style adopted by the project;
+- catch a number of errors in your code.
+
+They're pretty fast, don't hesitate!
+
+```sh
+source ./env/bin/activate
+./scripts-dev/lint.sh
+```
+
+Note that this script *will modify your files* to fix styling errors.
+Make sure that you have saved all your files.
+
+If you wish to restrict the linters to only the files changed since the last commit
+(much faster!), you can instead run:
+
+```sh
+source ./env/bin/activate
+./scripts-dev/lint.sh -d
+```
+
+Or if you know exactly which files you wish to lint, you can instead run:
+
+```sh
+source ./env/bin/activate
+./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
+```
+
+## Run the unit tests (Twisted trial).
+
+The unit tests run parts of Synapse, including your changes, to see if anything
+was broken. They are slower than the linters but will typically catch more errors.
+
+```sh
+source ./env/bin/activate
+trial tests
+```
+
+If you wish to only run *some* unit tests, you may specify
+another module instead of `tests` - or a test class or a method:
+
+```sh
+source ./env/bin/activate
+trial tests.rest.admin.test_room tests.handlers.test_admin.ExfiltrateData.test_invite
+```
+
+If your tests fail, you may wish to look at the logs (the default log level is `ERROR`):
+
+```sh
+less _trial_temp/test.log
+```
+
+To increase the log level for the tests, set `SYNAPSE_TEST_LOG_LEVEL`:
+
+```sh
+SYNAPSE_TEST_LOG_LEVEL=DEBUG trial tests
+```
+
+
+## Run the integration tests ([Sytest](https://github.com/matrix-org/sytest)).
+
+The integration tests are a more comprehensive suite of tests. They
+run a full version of Synapse, including your changes, to check if
+anything was broken. They are slower than the unit tests but will
+typically catch more errors.
+
+The following command will let you run the integration test with the most common
+configuration:
+
+```sh
+$ docker run --rm -it -v /path/where/you/have/cloned/the/repository\:/src:ro -v /path/to/where/you/want/logs\:/logs matrixdotorg/sytest-synapse:buster
+```
+
+This configuration should generally cover  your needs. For more details about other configurations, see [documentation in the SyTest repo](https://github.com/matrix-org/sytest/blob/develop/docker/README.md).
+
+
+## Run the integration tests ([Complement](https://github.com/matrix-org/complement)).
+
+[Complement](https://github.com/matrix-org/complement) is a suite of black box tests that can be run on any homeserver implementation. It can also be thought of as end-to-end (e2e) tests.
+
+It's often nice to develop on Synapse and write Complement tests at the same time.
+Here is how to run your local Synapse checkout against your local Complement checkout.
+
+(checkout [`complement`](https://github.com/matrix-org/complement) alongside your `synapse` checkout)
+```sh
+COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh
+```
+
+To run a specific test file, you can pass the test name at the end of the command. The name passed comes from the naming structure in your Complement tests. If you're unsure of the name, you can do a full run and copy it from the test output:
+
+```sh
+COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh TestBackfillingHistory
+```
+
+To run a specific test, you can specify the whole name structure:
+
+```sh
+COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh TestBackfillingHistory/parallel/Backfilled_historical_events_resolve_with_proper_state_in_correct_order
+```
+
+
+### Access database for homeserver after Complement test runs.
+
+If you're curious what the database looks like after you run some tests, here are some steps to get you going in Synapse:
+
+ 1. In your Complement test comment out `defer deployment.Destroy(t)` and replace with `defer time.Sleep(2 * time.Hour)` to keep the homeserver running after the tests complete
+ 1. Start the Complement tests
+ 1. Find the name of the container, `docker ps -f name=complement_` (this will filter for just the Compelement related Docker containers)
+ 1. Access the container replacing the name with what you found in the previous step: `docker exec -it complement_1_hs_with_application_service.hs1_2 /bin/bash`
+ 1. Install sqlite (database driver), `apt-get update && apt-get install -y sqlite3`
+ 1. Then run `sqlite3` and open the database `.open /conf/homeserver.db` (this db path comes from the Synapse homeserver.yaml)
+
+
+# 9. Submit your patch.
+
+Once you're happy with your patch, it's time to prepare a Pull Request.
+
+To prepare a Pull Request, please:
+
+1. verify that [all the tests pass](#test-test-test), including the coding style;
+2. [sign off](#sign-off) your contribution;
+3. `git push` your commit to your fork of Synapse;
+4. on GitHub, [create the Pull Request](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request);
+5. add a [changelog entry](#changelog) and push it to your Pull Request;
+6. for most contributors, that's all - however, if you are a member of the organization `matrix-org`, on GitHub, please request a review from `matrix.org / Synapse Core`.
+7. if you need to update your PR, please avoid rebasing and just add new commits to your branch.
+
+
+## Changelog
+
+All changes, even minor ones, need a corresponding changelog / newsfragment
+entry. These are managed by [Towncrier](https://github.com/hawkowl/towncrier).
+
+To create a changelog entry, make a new file in the `changelog.d` directory named
+in the format of `PRnumber.type`. The type can be one of the following:
+
+* `feature`
+* `bugfix`
+* `docker` (for updates to the Docker image)
+* `doc` (for updates to the documentation)
+* `removal` (also used for deprecations)
+* `misc` (for internal-only changes)
+
+This file will become part of our [changelog](
+https://github.com/matrix-org/synapse/blob/master/CHANGES.md) at the next
+release, so the content of the file should be a short description of your
+change in the same style as the rest of the changelog. The file can contain Markdown
+formatting, and should end with a full stop (.) or an exclamation mark (!) for
+consistency.
+
+Adding credits to the changelog is encouraged, we value your
+contributions and would like to have you shouted out in the release notes!
+
+For example, a fix in PR #1234 would have its changelog entry in
+`changelog.d/1234.bugfix`, and contain content like:
+
+> The security levels of Florbs are now validated when received
+> via the `/federation/florb` endpoint. Contributed by Jane Matrix.
+
+If there are multiple pull requests involved in a single bugfix/feature/etc,
+then the content for each `changelog.d` file should be the same. Towncrier will
+merge the matching files together into a single changelog entry when we come to
+release.
+
+### How do I know what to call the changelog file before I create the PR?
+
+Obviously, you don't know if you should call your newsfile
+`1234.bugfix` or `5678.bugfix` until you create the PR, which leads to a
+chicken-and-egg problem.
+
+There are two options for solving this:
+
+ 1. Open the PR without a changelog file, see what number you got, and *then*
+    add the changelog file to your branch (see [Updating your pull
+    request](#updating-your-pull-request)), or:
+
+ 1. Look at the [list of all
+    issues/PRs](https://github.com/matrix-org/synapse/issues?q=), add one to the
+    highest number you see, and quickly open the PR before somebody else claims
+    your number.
+
+    [This
+    script](https://github.com/richvdh/scripts/blob/master/next_github_number.sh)
+    might be helpful if you find yourself doing this a lot.
+
+Sorry, we know it's a bit fiddly, but it's *really* helpful for us when we come
+to put together a release!
+
+### Debian changelog
+
+Changes which affect the debian packaging files (in `debian`) are an
+exception to the rule that all changes require a `changelog.d` file.
+
+In this case, you will need to add an entry to the debian changelog for the
+next release. For this, run the following command:
+
+```
+dch
+```
+
+This will make up a new version number (if there isn't already an unreleased
+version in flight), and open an editor where you can add a new changelog entry.
+(Our release process will ensure that the version number and maintainer name is
+corrected for the release.)
+
+If your change affects both the debian packaging *and* files outside the debian
+directory, you will need both a regular newsfragment *and* an entry in the
+debian changelog. (Though typically such changes should be submitted as two
+separate pull requests.)
+
+## Sign off
+
+In order to have a concrete record that your contribution is intentional
+and you agree to license it under the same terms as the project's license, we've adopted the
+same lightweight approach that the Linux Kernel
+[submitting patches process](
+https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin>),
+[Docker](https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other
+projects use: the DCO (Developer Certificate of Origin:
+http://developercertificate.org/). This is a simple declaration that you wrote
+the contribution or otherwise have the right to contribute it to Matrix:
+
+```
+Developer Certificate of Origin
+Version 1.1
+
+Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
+660 York Street, Suite 102,
+San Francisco, CA 94110 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+If you agree to this for your contribution, then all that's needed is to
+include the line in your commit or pull request comment:
+
+```
+Signed-off-by: Your Name <your@email.example.org>
+```
+
+We accept contributions under a legally identifiable name, such as
+your name on government documentation or common-law names (names
+claimed by legitimate usage or repute). Unfortunately, we cannot
+accept anonymous contributions at this time.
+
+Git allows you to add this signoff automatically when using the `-s`
+flag to `git commit`, which uses the name and email set in your
+`user.name` and `user.email` git configs.
+
+
+# 10. Turn feedback into better code.
+
+Once the Pull Request is opened, you will see a few things:
+
+1. our automated CI (Continuous Integration) pipeline will run (again) the linters, the unit tests, the integration tests and more;
+2. one or more of the developers will take a look at your Pull Request and offer feedback.
+
+From this point, you should:
+
+1. Look at the results of the CI pipeline.
+   - If there is any error, fix the error.
+2. If a developer has requested changes, make these changes and let us know if it is ready for a developer to review again.
+3. Create a new commit with the changes.
+   - Please do NOT overwrite the history. New commits make the reviewer's life easier.
+   - Push this commits to your Pull Request.
+4. Back to 1.
+
+Once both the CI and the developers are happy, the patch will be merged into Synapse and released shortly!
+
+# 11. Find a new issue.
+
+By now, you know the drill!
+
+# Notes for maintainers on merging PRs etc
+
+There are some notes for those with commit access to the project on how we
+manage git [here](docs/development/git.md).
+
+# Conclusion
+
+That's it! Matrix is a very open and collaborative project as you might expect
+given our obsession with open communication. If we're going to successfully
+matrix together all the fragmented communication technologies out there we are
+reliant on contributions and collaboration from the community to do so. So
+please get involved - and we hope you have as much fun hacking on Matrix as we
+do!

-# Setting up Synapse with Workers using Docker Compose
-
-This directory describes how deploy and manage Synapse and workers via [Docker Compose](https://docs.docker.com/compose/).
-
-Example worker configuration files can be found [here](workers).
-
-All examples and snippets assume that your Synapse service is called `synapse` in your Docker Compose file.
-
-An example Docker Compose file can be found [here](docker-compose.yaml).
-
-## Worker Service Examples in Docker Compose
-
-In order to start the Synapse container as a worker, you must specify an `entrypoint` that loads both the `homeserver.yaml` and the configuration for the worker (`synapse-generic-worker-1.yaml` in the example below). You must also include the worker type in the environment variable `SYNAPSE_WORKER` or alternatively pass `-m synapse.app.generic_worker` as part of the `entrypoint` after `"/start.py", "run"`).
-
-### Generic Worker Example
-
-```yaml
-synapse-generic-worker-1:
-  image: matrixdotorg/synapse:latest
-  container_name: synapse-generic-worker-1
-  restart: unless-stopped
-  entrypoint: ["/start.py", "run", "--config-path=/data/homeserver.yaml", "--config-path=/data/workers/synapse-generic-worker-1.yaml"]
-  healthcheck:
-    test: ["CMD-SHELL", "curl -fSs http://localhost:8081/health || exit 1"]
-    start_period: "5s"
-    interval: "15s"
-    timeout: "5s"
-  volumes:
-    - ${VOLUME_PATH}/data:/data:rw # Replace VOLUME_PATH with the path to your Synapse volume
-  environment:
-    SYNAPSE_WORKER: synapse.app.generic_worker
-  # Expose port if required so your reverse proxy can send requests to this worker
-  # Port configuration will depend on how the http listener is defined in the worker configuration file
-  ports:
-    - 8081:8081
-  depends_on:
-    - synapse
-```
-
-### Federation Sender Example
-
-Please note: The federation sender does not receive REST API calls so no exposed ports are required.
-
-```yaml
-synapse-federation-sender-1:
-  image: matrixdotorg/synapse:latest
-  container_name: synapse-federation-sender-1
-  restart: unless-stopped
-  entrypoint: ["/start.py", "run", "--config-path=/data/homeserver.yaml", "--config-path=/data/workers/synapse-federation-sender-1.yaml"]
-  healthcheck:
-    disable: true
-  volumes:
-    - ${VOLUME_PATH}/data:/data:rw # Replace VOLUME_PATH with the path to your Synapse volume
-  environment:
-    SYNAPSE_WORKER: synapse.app.federation_sender
-  depends_on:
-    - synapse
-```
-
-## `homeserver.yaml` Configuration
-
-### Enable Redis
-
-Locate the `redis` section of your `homeserver.yaml` and enable and configure it:
-
-```yaml
-redis:
-  enabled: true
-  host: redis
-  port: 6379
-  # password: <secret_password>  
-```
-
-This assumes that your Redis service is called `redis` in your Docker Compose file.
-
-### Add a replication Listener
-
-Locate the `listeners` section of your `homeserver.yaml` and add the following replication listener:
-
-```yaml
-listeners:
-  # Other listeners
-
-  - port: 9093
-    type: http
-    resources:
-      - names: [replication]
-```
-
-This listener is used by the workers for replication and is referred to in worker config files using the following settings:
-
-```yaml
-worker_replication_host: synapse
-worker_replication_http_port: 9093
-```
-
-### Add Workers to `instance_map`
-
-Locate the `instance_map` section of your `homeserver.yaml` and populate it with your workers:
-
-```yaml
-instance_map:
-  synapse-generic-worker-1:        # The worker_name setting in your worker configuration file
-    host: synapse-generic-worker-1 # The name of the worker service in your Docker Compose file
-    port: 8034                     # The port assigned to the replication listener in your worker config file
-  synapse-federation-sender-1:
-    host: synapse-federation-sender-1
-    port: 8034
-```
-
-### Configure Federation Senders
-
-This section is applicable if you are using Federation senders (synapse.app.federation_sender). Locate the `send_federation` and `federation_sender_instances` settings in your `homeserver.yaml` and configure them:
-
-```yaml
-# This will disable federation sending on the main Synapse instance
-send_federation: false
-
-federation_sender_instances:
-  - synapse-federation-sender-1 # The worker_name setting in your federation sender worker configuration file
-```
-
-## Other Worker types
-
-Using the concepts shown here it is possible to create other worker types in Docker Compose. See the [Workers](https://matrix-org.github.io/synapse/latest/workers.html#available-worker-applications) documentation for a list of available workers.
